In many elementary and middle schools, STEM is still packaged as disconnected mini-lessons or worksheet-based challenges—“build a tower out of straws,” “calculate this robot path,” or “color code a circuit.” But we increasingly see that unless STEM is anchored in meaningful inquiry, with rich authentic materials and 21st-century thinking, it fails to deliver the deeper learning, motivation, and scientific habits students need and administrators and curriculum leaders should prioritize. Failure to do so is a fundamental failure of leadership and a profound disconnect in preparing students to succeed in the 21st century.
Teachers, STEM coordinators, curriculum designers, Camp and School leaders have a responsibility to move beyond superficial STEM tasks and embrace projects that mirror real-world phenomena: 3D printing of custom parts, designing solar-powered systems, laser engraving prototypes, flying drones to collect sensor data, building model jet engines, or doing “real” chemistry via meaningful and useful data collection. These are the tasks that build scientific thinking, engineering habits of mind, computational literacy, and cross-disciplinary skills.
Real-world STEM matters. How it connects to our national math and science performance challenges is important. Why we should be wary of overly simplistic—and potentially unsafe—practices like reusing toilet-paper tubes in classroom kits without hygiene protocol are important considerations.
What “Real” STEM and 21st-Century Skills Look Like
Real STEM is based on inquiry-driven, open-ended challenges are the backbone of developing the next generation of scientists. Instead of telling students exactly what to build, ask them to pose questions: “How can I make a small wind turbine that powers an LED?” or “What design of propeller gives maximal thrust for minimal energy?” or “What can we learn about the public water supply through aquarium water quality testing?” Students should design, iterate, test, collect data, reflect, and revise. This kind of inquiry builds not just content knowledge but also creativity, persistence, argumentation, and metacognition.
Real STEM is hands-on with modern technologies. It incorporates tools and platforms that reflect current industry trends. For example:
- 3D printing allows students to fabricate unique parts (gears, prototypes, enclosures) and rapidly iterate designs.
- Solar and renewable energy kits let learners test real PV output, angle optimization, storage trade-offs, and system integration preparing for a world that increasingly is reliant on non-fossil fuel energies.
- Laser engraving / cutting enables precise fabrication of parts or sensors encasements.
- Drones equipped with sensors can map terrain, temperature, or vegetation in local environments.
- Model jet engines / small turbines (or simplified air/steam turbine setups) help students engage with fluid dynamics, energy conversion, and measurement under real constraints.
- Chemistry with data logging: Rather than pre‑packaged “safe” kits, the richest chemistry labs let students experiment with growth or reaction rates, titrations, pH sensors, spectrophotometry, or digital probes—gathering real datasets to analyze trends, fit models, and reason about uncertainties.
These tools offer more than novelty—they create generative contexts where students can ask new questions, tinker with design space, and experience iterative improvement.
21st-century skills should be embedded from early elementary school onward. In real STEM projects, communication, collaboration, critical thinking, digital literacy, project management, and data fluency become essential. Students learn to interpret data visualizations, debug prototypes, negotiate trade-offs, version control, and document processes.
When STEM is just a “fun activity,” these higher-order habits often get omitted. But in authentic inquiry, they are integral.
The U.S. Performance Context: Why This Matters
It’s not just idealism to call for stronger STEM; our national data underscores urgency.
- The latest TIMSS (2023) results show that U.S. fourth- and eighth-grade math performance has declined compared to 2019.
- In science, fourth-grade scores are now at their lowest since the first TIMSS cycle in 1995. Read that again. This is the lowest since many of today’s teachers were in school. Our current systems and models from last century have not demonstrated that they work for our youth.
- On the global stage, U.S. students routinely underperform peers in many high-performing systems.
- Recent PISA assessments also show that U.S. 15-year-olds dropped ~13 points in math compared to prior cycles and remain near the global average in science, but with widening internal disparities.
These declines are not just abstract—they suggest growing deficits in quantitative reasoning, engineering thinking, and scientific literacy at a time when the workforce demands stronger STEM foundations. If STEM remains shallow, we worsen the gap.
Real STEM activities help bridge this gap by letting students apply mathematics, reasoning, computational thinking, and experimentation—not just memorize formulas.
Why Inquiry-Based, Hands-On STEM Works
The educational research base strongly supports inquiry-driven, hands-on STEM over passive or scripted tasks. Students engaged in inquiry:
- Develop deeper conceptual understanding, because they explore causes, test hypotheses, and experience the tension of real systems.
- Retain interest and motivation—authentic challenge fosters ownership, curiosity, and agency.
- Transfer skills across domains—data reasoning, modeling, iteration, and design thinking generalize beyond the specific activity.
- Experience the messiness and uncertainty of real science, preparing them for future research or engineering practice.
A Hygiene Warning: Beware of Recycled Toilet-Paper Tubes Without Protocols
In many STEM kits, a go-to cheap material is the humble toilet-paper tube (or paper towel roll). While inexpensive and readily available, relying on recycled tubes—especially with multiple students handling them—poses a risk of disease transmission if hygiene is not tightly managed.
Objects like paper tubes are fomites—abiotic vectors that can transmit pathogens (viruses, bacteria, fungi) from touched surfaces to new hosts. Pathogen persistence on inanimate surfaces has been well documented. Given that paper tubes absorb moisture (from their humble commode-side beginnings) and may retain viral fragments given their proximity to excrement, repeated handling by many students over days without decontamination poses tangible risk, especially in cold and flu season or amid COVID concerns. Below are some specific concerns about use of:
- Shared handling: If students swap or pass tubes, residues from coughs, sneezes, or unwashed hands may accumulate.
- Absorbency & internal surfaces: Tubes are porous, so they may trap droplets in fibers or inner layers, possibly preserving viral particles internally where cleaning is difficult.
- Difficulty of decontamination: Cleaning or disinfecting paper tubes without degradation is nontrivial—spraying bleach or alcohol can compromise structural integrity.
- Aerosolization risk: In restrooms, flushing has been shown to generate aerosols carrying microbes—this illustrates how even everyday activities can aerosolize pathogens. While toilet tube reuse is not the same, it underscores the fluid dynamics of droplets and aerosol transmission in shared air.
Integrating Real STEM Into Elementary & Middle Grades
Here’s how teachers and STEM coordinators can make this work in practice:
- Start with a compelling question or challenge.
- Provide choice in materials and tools.
- Scaffold a measurement culture.
- Encourage iteration and failure.
- Embed cross-disciplinary links.
- Show public sharing and peer review.
- Maintain hygiene practices in materials use.
By taking this approach, STEM classes become something more than a fun break—they become microcosms of real scientific or engineering work.
In a global environment where U.S. students are slipping in math and science performance, we cannot afford to relegate STEM to superficial tasks. Teachers, coordinators, and curriculum leaders must commit to meaningful inquiry-based, hands-on STEM that mirrors real-world engineering, chemistry, data science, and design. Technologies like 3D printing, solar (PV) systems, drones, laser fabrication, and data-logging chemistry open doors to richer learning and deeper skills.
At the same time, we need to balance ingenuity with safety. The use of recycled toilet paper tubes in STEM kits, while economical, carries nontrivial disease transmission risk. In an era of flu, COVID, and other infectious threats, educators must evaluate the trade-offs in materials carefully.
If we succeed, we give students not just content knowledge but dispositions as problem solvers, data thinkers, collaborators, and innovators. Those attributes are precisely what will help close our national STEM gap—and better prepare the next generation to compete, create, and meaningfully contribute in a complex world.
